A Single-Antenna Method and Post-Processing Strategy for Radar Cross-Section Measurements at Near-Field Ranges [PDF]

open access: yesSensors, 2022
The single-antenna technique proposed in this paper was developed for measuring the radar cross-section at near-field distances in a real environment, from reflection coefficient measurements on the antenna.

Simulation of the Radar Cross Section of a Noctuid Moth [PDF]

open access: yesRemote Sensing, 2022
Electromagnetic modelling may be used as a tool for understanding the radar cross section (RCS) of volant animals. Here, we examine this emerging method in detail and delve deeper into the specifics of the modelling process for a single noctuid moth ...

The Calculation and Analysis of the Bistatic Quantum Radar Cross Section for the Typical 2-D Plate

open access: yesIEEE Photonics Journal, 2018
The quantum radar cross section (QRCS) describes how much return one gets when illuminating an object with a handful of photons. However, the previous studies mainly focused on the monostatic scattering of quantum radar.

Analysis of Quantum Radar Cross-Section by Canonical Quantization Method (Full Quantum Theory)

open access: yesIEEE Access, 2020
This article investigates the difference between two quantum-based theories to calculate the radar cross-section (RCS). Quantum radar cross-section (QRCS) has been commonly analyzed using the dipole approximation method, and the related results show that

Wideband RCS reduction due to plasma generated by radioactive nuclei for cylindrical object

open access: yesScientific Reports, 2022
Radar cross section reduction has been one of the most important research topics in recent years. Plasma-based stealth is a method of reducing the radar cross section, which dampens the electromagnetic waves and reduces the amount of return waves.
